INTRAVENOUS 363 



1. Anaesthetise the animal and secure it firmly to 

 the operating table. 



2. Irrigate the conjunct! val sac thoroughly with 

 sterile saline solution. 



3. Make an incision through the upper quadrant of 

 the cornea into the anterior chamber by means of a 

 triangular keratome. 



4. Separate the lips of the corneal wound with a 

 flexible silver spatula; seize the solid inoculum in a 

 pair of iris forceps, introduce it through the corneal 

 wound, and deposit it on the anterior surface of the 

 iris; withdraw the forceps. 



5. Again irrigate the sac and the surface of the cor- 

 nea. 



6. Release the animal from the operating table. 



7. Label, etc. 



7. Intrapulmonary. 



Fluid Inoculum. (Anesthetic, none.) 



1. Have the animal firmly held by an assistant. 

 (In this case the foreleg of the selected side is drawn up 

 by the assistant and held with the ear of that side.) 



2. Shave carefully in the axillary line and disinfect 

 the denuded skin. 



3. Thrust the needle of the syringe boldly through 

 the fifth or sixth intercostal space into the lung tissue. 



4. Inject the contents of the syringe slowly. 



5. Label, etc. 



8. Intravenous. 



Fluid Inoculum. (Anesthetic, none.)

 perform the inoculation satisfactorily a general anaes-
